As with many parts of the body, I saw a documentary about how the brain can regenerate, it was believed that it couldn't but some research has shown some parts of it can repair neurons!!
But on a lighter note, the fogginess does subside with more time, when I first quit I sometimes thought I had better mental ability when drinking or hungover, as for the first few weeks I was forgetting things all the time, which I never had done before!!
Give it time!!
